But that's not why I'm posting this. I'm posting it because of the following comment, found at Pharyngula:

Here in Italy the UUAR (italian acronym for Atheists and Agnostic Rationalists union) tried to put the same message on a bus in Genoa, but the advertisement society refused.In a more recent episode, the UUAR put up signs with the same message (The bad news is that god doesn't exists...) and the signs were taken down by police because it offended religious sentiment.

In a funny aftermath, the UUAR choose a substitute message:"The bad news is that Zeus doesn't exists. The good news is you can say that about Zeus".
